Chien
Khan negotiates with a demon lord named Noi Tai Dar. Khan offers the
souls of all mankind to the hellspawn, as he seeks vengeance against
humanity and wishes to see them destroyed. Noi Tai Dar states that
if Chien Khan will open a doorway for him, he will see it done. To
open the passage, Khan must sacrifice a life and the Warrior Dragon
must unleash the power of the nuclear power plant.

Meanwhile,
the Dragon, under the control of Khan, begins to destroy the nuclear
power plant. The TMNT attack their friend to try to stop him, to no
avail. Ninjara is enraged when she discovers that the Warrior Dragon
has been ordered to destroy the power plant - she is disgusted that
Chien Khan would allow more radiation to foul Japan considering the
bombing in 1945.

Chien
Khan prepares the young girl for sacrifice while the damaged nuclear
power plant opens the gateway for the massive demon. The hellspawn
attacks the Dragon, who comes to his senses after being blasted by
a bolt of energy. The mighty Warrior is dismayed at what his actions
have caused.

Master
Splinter tries to meditate to find a solution to their enormous problem
as the Warrior Dragon attacks the demon. The Sensei notes that he
feels another great presence nearby...

Leo
asks Ninjara what Chien Khan has planned, and she reveals that the
summoning requires both a power source and a sacrifice. Apparently
Khan hasn't performed the sacrifice yet, as Noi Tai Dar is still tied
to his power source - but once Khan completes his part of the ritual,
the demon will be free to destroy all humanity. Leo determines that
since the demon is too powerful for them to fight, they must stop
Khan from making his sacrifice. Ninjara states that his headquarters
are far from where they are, and Leonardo tells her that gives them
all the more reason to hurry.

Master
Splinter stays in his meditative state, noting that the spirits are
coming closer... behind him, two gigantic forms begin to appear in
the sky... it's none other than the gods, Izanagi and Izanami!

Fu
Sheng breaks free of his bounds and smashes into Chien Khan, preventing
him from sacrificing the girl.

Izanagi
blasts Noi Tai Dar with a beam of light from his eyes and destroys
the demon.

Chien
Khan's helmet is knocked off by Fu Sheng's attack - revealing Khan
to be a dog-faced man! Chien punches a shocked Fu Sheng in the face
and then returns to his sacrifice, but the TMNT and Ninjara arrive
in time to stop him. Khan is livid and calls Ninjara a traitor before
ordering his henchmen to kill our heroes - but the villains are no
much for the Turtles and their new foxy ally. Suddenly, the roof of
the building is ripped apart by the Warrior Dragon, who has returned
to save his friend Fu Sheng. The old man is fine, but Chien uses the
distraction to strike Ninjara and make his escape.

Raph
helps Ninjara to her feet, and everyone breathes a sigh of relief
for another hard fought victory.
